upgrade from 9.04 to 9.10 hangs during 'getting new packages' (libapt download problem?)

[Jamie Strandboge]

Binary package hint: update-manager

On on up to date Ubuntu 9.04 system, I perform in a terminal:
$ sudo update-manager -d

I click through the defaults and the upgrade starts:
* Preparing the upgrade (finishes)
* Setting new software channels (finishes)
* Getting new packages (gets to 'Fetching file 1896 of 1896) and stops

The 'Terminal' option is grayed out, so I don't see what is going on. Will attach files from /var/log/dist-upgrade. I do have apt-listchanges installed along with unattended upgrades enabled.

Not attaching term.log-- it's empty.

[Jamie Strandboge (jdstrand)]

/var/log/apt/term.log only has information from the last upgrade within jaunty (ie, the recent tzdata upgrade).

[Jamie Strandboge (jdstrand)]

Looking at the ps output, I see:
root 4539 1.4 0.1 5500 2188 pts/0 S+ 12:37 2:56 /usr/lib/apt/methods/http

I use a local mirror and all the packages for the upgrade were downloaded within a few minutes.

[Jamie Strandboge (jdstrand)]

I killed the http process and update-manager went away. I this tried the upgrade again and it got past this point and is installing now. It is clear to me what went wrong because I got no feedback from update-manager. If it was a networking problem, perhaps a timeout of some sort would be in order to give the user some feedback.

I think that the bug comes from your local mirror and not from update-manger.

[Jamie Strandboge (jdstrand)]

Perhaps, but it seems that the upgrade process should have handled this better.

I have the same problem. It has stopped at "Fetching file 1294 of 1294". I have the amd64 version witch Croatian language.

[Marko Vodanovic (morgoth84)]

I've left it for a couple of hours to see if it would budge, but it didn't. So I closed the upgrade setup, killed the karmic process and started the upgrade again (Alt+F2, update-notifier-kde -u). Now it's working ok. It's installing new packages so hopefully in 15 minutes or so it will be done...

Same problem here - stuck at "Fetching file 1226 of 1226" and has been stuck there overnight. i386 edition, US English. Using the Internode (Australia) mirror. I'll retry as mentioned by Jamie (#6).

[chuq (chuq)]

..and the workaround worked for me!

[scg34 (s-c-graham)]

Just to confirm - I saw the same behaviour (upgrade-manager hung on fetching the last file), but killing the upgrade-manager and then re-starting the upgrade worked fine.

[Robin Stocker (nibor)]

Same problem here, hangs on fetching the last file (2021 of 2021). Here's a backtrace:

I've got the same problem - updater constantly trying to fetch the last file and restarting the process again and again for some reason. But restarting the updater even several times didn't help. I was able to continue upgrading by removing this last package (in my case it was a manually installed from .deb nexuiz-data package; "sudo lsof | grep http | grep /var/cache/apt" during fetching helped to identify it).

[BJ (bryn-jones1)]

Okay - i think i've fixed this for me - i let it time out then it threw me an error unable to get package openexr6.deb (sorry i've shut the window now before i noted what it was.....) wo i installed this manually and boom 9.10 is now installing...... thats really sucky!!!

[Ville Pilvio (vpilvio)]

Just a ditto... the upgrade also hangs for me... will kill the process and restart the update. I fully agree, there should be a timeout action with some user feedback. Most end users will panic!

[Matt Dittloff (mattdittloff)]

Same thing here. The upgrade hangs after the new packages are downloaded. I clicked the Cancel button to exit out of the upgrade. In Update Manager, I clicked Distribuion Upgrade again, and now it is continuing on installing the packages that it downloaded.

[Michael Vogt (mvo)]

I have seen a similar hang before, it seems to be some sort of race condition in the libapt downloader. I have not found a way to reproudce it nor did I manage to get a gdb trace of it. If someone can find a way to reproduce the issue, I would be very thanksful.

[Jnik (grjohnis)]

got the same thing. Stuck while downloading the last package.
